Bilateral choroiditis as the only sign of persistent Mycobacterium intracellulare infection following haematogenous spread in an immunocompromised patient.

An immunocompromised patient had positive blood cultures for Mycobacterium intracellulare and no identifiable organ seeding was started on treatment. One month later, the patient was clinically well with negative blood cultures but drug-induced myelotoxicity had developed. Ocular fundus examination at this time revealed bilateral choroidal granulomas which changed patient management.
